One of the best ways to make your assignments, projects and presentations stand out is to have great images, especially if you are doing a multi-media presentation. Finding the images is usually not a problem, BUT, finding images that you can use without breaking can be. Using Creative Commons images is one way to avoid this problem (and of course you can use your own images as you own the Copyright).
Here is a list of websites that will give you some incredible photographs and images that will help make your assignments stand out. Remember though, even if the images are Creative Commons or Copyright free, you must still reference them. To help you to do this correctly go to Referencing to find the right citation format for images.
